Abstract

The invention relates to an electrode intended, for example, for electrocardiogram examinations, and capable of being held in position by suction. Vacuum conditions are created through a hose or tube (8), through which a measuring conductor (7) is drawn. The electrode comprises an inflexible backpiece (3), an intermediate component (2) made of an elastomeric material, and an electrode plate (1), preferably made of a silver-coated plastics. The intermediate component (2) includes a relatively inflexible sealing ring (9) which, in the operative state of the electrode, supports against the skin of a patient via a sealing lip (13) and against the opposing side of the backpiece (3). The electrode plate (1) is firmly connected to the backpiece, while the sealing ring carried by the intermediate component (2) is movable and can be readily sprung away from the backpiece (via resilient means 17). When no load is exerted on the lip-side of the ring and the ring is thus urged outwardly, a vacuum valve is closed automatically through the intermediate component (2), and is re-opened when the electrode is pressed against the surface of the skin, whereupon the electrode is held firmly by suction.
